E .A/A THA A/ A T TORNEY Patented Feb. 6, 1951 UNITED STATES PATENTOFFICE 2 Claims.

This invention pertains to spectacle cases, wherein the spectacles arepositioned medially on blocks secured within the pocket portions of saidspectacle cases. t is the object of this invention to provide a block ofnovel construction adapted for use with spectacle cases, said blockbeing practically indestructible in use and serving to facilitate themanufacture of the spectacle case with the block therein.

These and other advantageous objects, which will appear from thedrawings and from the description hereinafter, are accomplished by thestructure of my invention, of which an embodiment is illustrated in theaccompanying drawings. it will be apparent, from a consideration of saiddrawings, and the following description, that the invention may beembodied in other forms suggested thereby. Such other forms as comewithin the scope of the appended claims are to be considered within thescope and purview of the instant invention.

In the drawings:

Fig. 1 is a perspective view of the blank from which the block of myinvention is manufactured, said blank being shown in its initial flatform,

Fig. 2 is a perspective view thereof, showing the blank in folded,assembled condition,

Fig. 3 is a vertical, end elevational view, taken on line 33 of Fig. 2,

Fig. 4 is a fragmentary, transverse, sectional view taken on line 44 ofFig. 5, showing the block in the pocket portion of the spectacle case,and

Fig. 5 is a top plan view of a spectacle case in which the block ispositioned.

In Fig. 1 of the drawings, there is shown a blank it from which theblock of my invention is made, said blank being preferably of metal orother material and having spaced front wall flanges H, H formed alongone longitudinal edge thereof, and spaced rear wall flanges 2E], 25'formed along the opposite longitudinal edge thereof. The flanges I I, ll are provided at their inner ends with spaced, opposed arcuate portionsl2, l2. The blank includes a medial portion [5 having a longitudinaledge M located between the arcuate portions i2, I2. The block is formedas shown in Fig. 2, by medially bending the blank to substantiallyU-shaped form to define an arcuate top 22 from which depend spacedparallel side walls 23, 23', the front wall flanges I I, l I beingdisposed at substantially right angles to said side walls and definingthe front wall portion of the block, the rear wall flanges 20, 20 beinglikewise disposed at substantially right angles to the side walls 23,23' of the block and defining the rear wall portion of the block. Thefront and rear wall portions of the block are bent along lines I3, [3,2|, 2|, so as to be angularly disposed downwardly and inwardly (see Fig.4) to conform to the arcuate outline of the inner surface of the bottomof the pocket P of the spectacle case S. The front wall flanges H, i iare provided with semicircular recesses l6, l6 which, in the assembledblock (see Fig. 2), define an opening I? through which the fastenerelement 2'? may be passed, said fastener element being projected throughthe wall of the pocket portion P of the spectaclecase s and engaging,and being secured to, the outer fastener element 23. The latter isadapted to have complementary engagement with the fastener 29 on theflap F of the spectacle case.

From a consideration of the drawings and the foregoing description, itwill be apparent that the block may be readily manufactured at low costand, even if made of comparatively light sheet metal, will haveconsiderable inherent rigidity.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

l. A block for spectacle cases constructed from a flat, bendable blankand having side wall portions and a medial portion therebetween andunitary therewith, and having spaced flanges along the longitudinaledges of said side wall portions bent in one direction at substantiallyright angles to the plane of said wall portions to definethe front andrear walls of said block, the opposed edges of said front wall flangeshaving complementary recesses defining an aperture through which afastener element may be passed, said blank being bent mediallylongitudinally to position the side walls in spaced parallel relationwith the medial portion defining the top of the block.

2. A block for spectacle cases constructed from a flat, bendable blankand having side wall portions and a middle portion therebetween andunitary therewith, and having spaced front Wall flanges along alongitudinal edge of said side wall portions bent in one direction atsubstantially right angles to the plane of said side wall portions todefine the front walls of said block, said flanges being provided attheir inner ends with complementary arcuate portions, said blank beingbent medially longitudinally to substantially U-shaped form to define anarcuate top from which depend the spaced side walls, said arcuate topbeing of complementary outline to the said combined arcuate portions ofsaid flanges.
